The gear 26is adapted to mesh with the three-step bevel gear 28, whereby differentspeeds may be obtained. The extended hub '12 of the traction wheel 12 is28 is adapted to slide longitudinally on said key, the sliding movementbeing controlled bythe lever 30. The gear 26 is also longie tudinallyadjustable on the shaft 25, for

Removable tires are providedfor the traction wheels 11 and 12. 1 Thesetires comprise tread bands 31,-adapted to circunu scribe the rims 12 and11 ,'being clamped rigidly on the peripheries of said rims by suitablemeans, as for example, bolts 32 op erating in out-turned lips or flanges81 for drawing the members 31 taut around the rims 11 and 12?.areattached at intervals to the outer peripheries of the members 31. Theadvantage of e the removable traction tires is obvious, ins

asmuch as it is objectionable to operate vehicles having rigid grippingor puncturing devices on the peripheries of their wheels,on thehighwaysor improved roads throughout the country, while such devicesare'practically a necessity when operating the vehicle'on soft ground.In my improved construction the traction tlres are employed when thevehicle and consorts are used for plowlng, cultivating,

vehicle forhauling produce to market,"the traction tires are easily andquickly removed leaving smooth wheel tires. that do not damage the road.I

.The foregoing description, 'in connection with the accompanyingdrawings, sets forth I 'struction, design and relative arrangementof'elements, that can be made without departure from the spirit of theinvention. Therefore I am not confined to this specification only so faras the limitation of the following claims.

Having now described my invention, what I claim and desire to secure byLetters Patent is. w

1. In a tractor, the combination of a motor cycle frame; a motor carriedon said frame a steering member mounted forward in said'frame; a pilotwheel carried by said steering member; co-acting spiral gears foroscillating said steering member; a steering rod for manually operatingsaid spiral gears; a rear axle connected with the frame; traction wheelsmounted on said axle; a series of beveled variable speed gears at tachedto the hub of one of the traction wheels; a drive shaft having spiralgear connection with the motor; a bevel pinion carried by said shaft;said bevelpinion being adapted to meshfwith the bevel gears onthe'traction wheel hub; means for shift- 4 ing the relation of thebevel'gea'rsand pinion; and clutch mechanism for connecting said bevelpinion with the. drive shaft.

2. In :a tractor, the combination of a motor cycle frame; a motorcarried on said frame; a steering member mounted forward In said frame;a p1lot wheel mounted on' for oscillating said steering member; a

ally adjustable traction wheelsmounted on said steering member;co-acting spiral gears said axle; an auxiliary frame connected with themain frame and withrthe rear axle I OlltSldB of'the traction wheels;anextended hub or sleeve on one of the traction wheels;

bevel gears of different diameters attached tQStlld sleeve; a driveshaft having spiral gear connection with the motor; a bevel pinionhaving clutch connection'with said drive shaft and adapted to mesh withthe bevel'gears on the traction sleeve; means for shifting saidpinion in'its relation to the bevel gears; and means for operating the clutch.

In testimony whereof I affix my signature.
